The grammar structure ~て頂戴(ちょうだい) is an informal way to make a request, meaning "please do ~". It attaches to the て-form of a verb and functions similarly to ~てください but with a softer, more casual tone.
~てちょうだい is predominantly used in casual, familiar speech. It is most commonly heard from women, mothers speaking to children, or older people addressing those close to them. It carries a warm, intimate, or sometimes slightly insistent tone that ~てください does not have.
Because of its casual and somewhat feminine or maternal register, it would sound out of place in formal or business settings. In those contexts, ~てください or ~ていただけますか would be appropriate instead.
For positive requests (asking someone to do something), simply attach ちょうだい to the て-form:
For negative requests (asking someone not to do something), use ~ないでちょうだい:
While the kanji form ちょうだい頂戴 exists, this grammar pattern is most commonly written in hiragana as ちょうだい when used as a request.
